If you have a new sexual partner, have concerns about possible exposure, or develop unexplained genital symptoms, appropriate testing is the most reliable way to find out.
9. Your Period Products May Affect Odor
Leaving a tampon in for too long can cause a very noticeable and unpleasant odor.
A retained tampon can also lead to serious complications, including toxic shock syndrome, although this is uncommon.
If you think you may have accidentally left a tampon inside, don't ignore it.
Seek medical assistance if you cannot remove it easily or if you develop concerning symptoms.
Always follow the recommended replacement intervals for menstrual products.
10. Diet and Lifestyle Can Play a Role
You may occasionally hear claims that specific foods dramatically change vaginal odor.
The evidence for many of these claims is limited.
However, body odor in general can be influenced by diet, hydration, sweating, medications, hormones, and other factors.
Drinking enough water and maintaining a balanced diet are sensible habits for overall health.
But you don't need to eliminate entire food groups simply because you notice a temporary change in vaginal scent.
When Is a Sour Smell Probably Not a Problem?
A mild sour or tangy scent may be completely normal when:
- There are no other symptoms
- The odor is relatively mild
- It resembles your usual scent
